Title: Improvements in and relating to electrical discharge erosion apparatus
IPC: B23H1/02
Filed: 1963-02-26
Abstract: 1,033,017. Electro erosion. ELOX CORPORATION OF MICHIGAN. Feb. 26, 1963 [Nov. 1, 1962], No. 7640/63. Heading B3V. [Also in Division H3] An electro-erosion apparatus comprises an energy storage means 12 charged from a direct current source 10 through switch 22 and discharged through switch 24, and including means whereby during both charging and discharging a mastering pulse is produced across the gap between electrode 14 and workpiece 18. The source may be a battery 10 or rectified alternating current. Switches 22, 24 may be gridtriggered devices such as thyratrons or ignitrons, but are preferably semi-conductors whose gating electrodes 22g, 24g are triggered alternately by pulses derived from pulsing means comprising a flip-flop stage 72 feeding alternately to one of a pair of one-shot multi-vibrator stages 74, 76, Fig. 3 (not shown). A pulse transformer 27 is provided in the discharge circuit to provide a machining pulse during both charging and discharging of capacitor 12. The machining pulses are fed through rectifier 54, and higher voltage ionization pulses are fed through rectifier 30 and resistor 52. A charging inductance is provided by primary winding 20a and separate inductance 20b and the discharge is effected through winding 21a and inductance 21b. Semi-conductor 22 is shunted by diode 32 and non-linear resistance cell 34, and also by network 40, 42, 44 to prevent a transient inverse voltage from appearing across the semiconductor at the beginning or end of its conductive stage. A similar circuit is provided across the discharge semi-conductor 24. Rectifiers 56, 60 shunted by silicon carbide cells 58, 62 are provided in the charge and discharge circuits and rectifiers 64, 68 in series respectively with silicon carbide cells 66, 70 are provided to stabilize the voltage on the capacitor 12 which is more than twice the source voltage 10. Transformer 27 may be replaced by two or more separate transformers. Two or more switches may also be provided in both the charge and discharge circuits for increasing the pulse rate.

Abstract: 1,256,147. Electrolytic capacitors. P. R. MALLORY & CO. Inc. 12 Feb., 1969 [14 Feb., 1968], No. 7685/69. Heading H1M. [Also in Division C7] Stainless steel member 10, forming part of the glass-metal seal for can 13 of a wet electrolytic capacitor (Figs. 4, 5, not shown), has a coating 11 which forms a barrier to diffusion of material to the stainless steel and a further coating 12 of solderable material whereby the seal is rendered solderable, as at 14, to the can. Coating 11 may be electroplated nickel, chromium or cobalt. Coating 12 may be an alloy of silver with gold, palladium, platinum, rhenium or osmium. The silver may be replaced by copper where sulphuric acid is not present. Layer 12 may be applied by electroplating a silver layer then a layer of the second metal and heating to 800-950‹ C. to alloy the layers, and the glass melting step can take place simultaneously. Alternatively the constituents of layer 12 can be co-deposited. The can metal may be silver, platinum, palladium or gold or a metal plated with one of these. A stainless steel can may be made solderable in the same way as the seal member, and if each is formed with separate layers of gold and silver they may be joined without the use of solder by heating to alloy the gold and silver (Fig. 3, not shown).

Filed: 1918-05-10
Abstract: 162,680. Hutchinson, G. May 10, 1918. Droppers. - In a wire fence dropper consisting of a notched solid rod or wire, the notches are formed by deformation of the wire by swaging &c. so that projecting portions are formed in the material near the notches, the crosssectional area of the dropper not being thereby reduced. In the form shown in Fig. 2, the projections are formed at the rear of the notches 2, the thickness on the line 11 being greater than at the position 10 so that the wires touch the dropper at the top and bottom of the notches. In the modification shown in Fig. 3, the droppers are bulged at the sides 13 of the notches 2. Connection of the wires to the droppers is effected by wire or sheet-metal staples 19, the legs 20a of which are normally in the form of arcs of circles and may be left unbent or be bent round the fence wires as shown in Fig. 1. To prevent lateral displacement of the dropper, the end 22 may be forced into the ground.

A method of making filter-tipped cigarettes by feeding stubs in alternation with unwrapped tobacco portions and enclosing the stubs and tobacco portions in a paper web to produce a composite continuous rod, includes the step of securing stiffening strips to the paper web in such a manner that a strip lies across the web adjacent each end of a stub, so that when the paper is folded about the tobacco portions and stubs, the strip forms a tubular reinforcement adjacent the stub. Tobacco is fed through a chimney 1 (Fig. 1) to the underside of a suction conveyer 2 which has perforations extending slightly less than the length of a double length tobacco portion of a filter cigarette. Cigarette portions 4 are formed thereon and trimmed by a trimmer 5. A paper wrapping strip 7 is drawn from a reel 8, gummed at 9 and provided with stiffening strips 15, cut from a strip 10 by a knife 13. Double length filter stubs 17 are supplied by a roller 18 to the gummed strip at a position between the stiffeners.

Patent GB-440861-A (GB)
Title: Improved method and device for the mechanical recording of sound or other oscillations
IPC: G11B3/00
Filed: 1935-03-15
Abstract: 440,861. Recording sound and the like. PHILIPS - MILLER NAAMLOOZE VENNOOTSCHAP, Emmasingel, Eindhoven, Holland. March 15, 1935, No. 8146. Convention date, March 22, 1934. [Class 40 (ii)] Relates to the mechanical recording on a carrier, such as a film, of sound or like oscillations, preferably for optical reproduction. According to the invention, near the point of recording a feeler is provided which coacts with the surface of the carrier to control an electric circuit in such a manner that the desired zero-position of the recording member is automatically maintained. Thus, defects due to irregularities in the thickness of the carrier or in the running of the film-supporting roller (where such is used), are eliminated. The Figure shows a recording apparatus in which a chisel having a V-shaped cutting edge acts upon a film 1 coated with an opaque layer. The chisel 2 is connected to an armature 15 surrounded by a coil 14 and mounted between pole-shoes 16, this assemblage being housed in a pivoted lever 18. A screw 19 enables the zero position of the chisel to be initially adjusted. Adjacent to the chisel, a feeler 8 which is mounted on a pivoted spring-controlled angle lever 9 bears on the film, the lever being connected to the diaphragm of a microphone 12. The coil 14 is connected in the output from an amplifier 13 for the audio-currents to be recorded, and the microphone 12 and a battery 22 are included in the output circuit. By this means, as the feeler follows the contour of the film surface, variations in the current through the microphone control the mean position of the recording tool. The microphone, which may be of any suitable type, preferably has a shock-proof mounting. A modification is described, Fig. 5 (not shown), in which instead of controlling the mean position of the chisel, the microphone currents, varied by the movements of the feeler, control the position of the lever 18. For this purpose, a second amplifier is employed, the output currents from which control the lever through a solenoid. In a further modification, instead of being connected to a microphone, the feeler actuates a shutter which controls the amount of light falling upon a photo-electric cell; the cell is connected to an amplifier by which currents are transmitted to the coil 14 for regulating the mean position of the chisel, or to a coil which controls the position of the lever 18.
